摘要
用非线性有限元法，分析在不同起爆方式下圆柱形装药爆炸时壳体的动力学响应。在原有的基础上，分析计算了端面两点对称起爆和两点偏心起爆。计算结果表明，起爆方式对爆炸作用有显著影响。
By means of the FE analysis of all-nonlinear dynamics,this paper presentsthe dynamic responses of cylindric case during the HE explosion influenced by differentdetonation modes. Modes of twopoint symmetric or nonsymmetric detonations are discussed.The computation results show that detonation mode affects the distribution andvariation of stress and strain。Of the above mentioned modes,the two-point symmetric detonation is more ideal.
